Yosys Build From Source Prerequisites

[dennowiggle]

I followed the readme file to build Yosys from source, but I got errors as some source files referenced by C #include code were missing.

I installed additional packages per the installation instruction on Yosys docs and that resolved the issue. I probably didn't need graphwiz and xdot to show schematics..... I didn't know you can show schematics from verilog code? Something else to explore....

sudo apt-get install build-essential clang bison flex \
   libreadline-dev gawk tcl-dev libffi-dev git make \
   graphviz xdot pkg-config python3 libboost-system-dev \
   libboost-python-dev libboost-filesystem-dev zlib1g-dev

On what OS did you build the source?

I could have installed some things on my 20.04 system due to other packages that I might have installed before I tested my build.

I used Debian 12 Bookworm x86_64 running under WSL2. As you suggest, I must have been missing some development packages that included the missing header files/libraries that you had already installed. I didn't keep a note of the exact compilation errors and missing files.

I didn't either. :-(

I aughtta at least do a clean install on one of my old boxes to verify this on latest version of Ubuntu (which has been my go-to desktop for a while now. The good news is that the versions of the pre-built packages on Ubuntu & the PI are probably good enough.

Or maybe I can scratch my instructions since the ones you point to look decent & likely to be maintained for the foreseeable future. Possibly even more-so now that, as you pointed out, Lattice has changed their license. :-/
